why the system reset every 3minutes?

[aaronxu]

I modified "pca10001\ble\experimental\ble_app_uart". I add 1 button(app_button.c) and 1 second Timer (app_timer.c)to display clock through UART to PC terminal.

But the system reset every 3minutes. Pls help me.

Thank you! It works well now! But another problem happened. Once I disconnect it from dongle, the system will be reset soon. What happened?

Yes.When I use lightblue to test device, it happens sometimes.
